--- Comment #13 from lsmod <forum+...@home.decotrain.de> --- Today I could get the hanger in Debian 12 starting https://slidealama.eu/ in Firefox. Again top shows the hang in Firefox. Started again gdb on this process with the same result: [New LWP 11245] [New LWP 11292] [New LWP 11320] [New LWP 11374] [New LWP 11442] [New LWP 11458] [New LWP 11460] [New LWP 11461] [New LWP 11462] [New LWP 11471] [New LWP 11472] [New LWP 11474] [New LWP 11489] [New LWP 11494] After that killing Firefox still freezes the complete system, but now it hangs in the plasmashell. Switching to another local console did not work.

Attaching to process 2015 After that there was no prompt or output and gdb simply blocked the ssh-shell. Even trying to open another gdb in a new ssh-shell did not work. warning: process 2015 is already traced by process 11731 ptrace: Die Operation ist nicht erlaubt. The PC did not react on ACPI-boot and a hard reset was needed. What can be tested now? -- You are receiving this mail because: You are watching all bug changes.
